flagged drive shown in the Installed Devices list.
If any drive is flagged as Not Installed, check the connector and
cable for that drive.
If the first drive is flagged as Not Installed, replace the primary
drive.
If all drives are flagged as Not Installed, replace the primary drive.
If any drive (other than the first drive) is flagged as Not Installed,
replace that drive.
If the problem remains, check the continuity on the drive cable and
replace the cable if necessary. If that does not fix the problem,
replace the system board.

shown is correct.
Note: The CD/DVD-ROM must be the last device installed and jumpers

Also ensure the CD/DVD-ROM cable is installed in connector

Type A-2 system board.
If any other adapter or device is flagged as
Not Installed

Check to see if any adapter or device is set to a conflicting address with any
other adapter or device. Also be sure that any adapter or device missing
from the list is not set to Disabled.
Note: If you cannot add a missing adapter or device to the list, the
diagnostic code for the missing adapter or device is not on the
diagnostic CD. Run the diagnostics provided with that device.
